I haven't listened to every Radiohead song they've ever released (I'm going through Spotify today and almost done), but I listened to In Rainbows in its entirety hundreds of times, and I think it's one of the best albums I've ever heard. In particular, 15 Step, and particularly that transition in the beginning, which blew my mind the first time I heard it, made quite an impression. Reckoner is one of the best songs I've ever heard, as well.
The King of Limbs I purchased day one digitally, and was disappointed, it definitely wasn't as good as In Rainbows, though it did have some great standout tracks, like Lotus Flower.
I just purchased the 24-bit WAV version of this album blind, having only heard Burn the Witch (pretty good), and Daydreaming (it's okay), based on the positive reviews here. I have Sennheiser HD598's and I'm listening on my computer. My question is: what program plays back 24-bit WAV the best? I did some searching and I came up with some mixed and garbage results. I'm currently using Adobe Audition CC 2015 since I thought that it might be the best to handle a high-quality format...thoughts, GAF?
Fake edit: I just listened to Decks Dark and Desert Island Disk, neither caught my interest. That said, I have definitely found that Radiohead albums can be like that, where it takes repeat listens to really sink in.
